1 Claim. (01. 16946) Our invention relates to fire extinguishers and hasfor an object to provide a fragile fire extinguishing material containerhaving means whereby the same may be exploded to scatter the material.

Another object of the invention is to provide a brittle container for afire extinguishing material with means whereby it may be thrown withforce.

A further object of this invention is to provide a glass or otherfragile container carrying an explosive cartridge and means whereby thesame may be exploded to shatter the container and scatter its contents.v

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawings inwhich:

Figure 1 is a vertical sectional view of our invention, v

Figure 2 is an elevational view thereof,

Figure 3 is an end view of Figure 2, and

Figure 4 is a detailed view of a trigger.

Figure 5 is a perspective view of the intersecting fins forming asteering device for the invention.

In the accompanying drawings as above enumerated and in the followingspecification, like characters of reference indicate like partsthroughout and in which l0, indicates our invention which consists of 9.preferably pear-shaped friable container ll, provided with a reducedneck l2, projecting from its enlarged or front end [3. The reduced tailend I, of the device is provided with a filler l5, through which isdrilled a bore 16, aligning with similar bores I1, in the opposing wallsof the member I I, whereby a cord 18, may be threaded there-through tothe outer end IQ, of which cord is secured a steering device 20.

The said neck I2, is externally screw-threaded to receive the innerthreaded tubular portion 2|, of a cartridge containing block 22,provided with an end bore 23, to receive a trigger member 24, the bore23, is enlarged at its inner end as at 25, in which said enlarged boreis seated an explosive cartridge 26. The member 24, comprises a shank21, an annular guide collar 28, and the inner end 29, of the shankterminates in a conical firing pin 30, the point 3|, of which normallyseats against the cap end 32, of said cartridge. The outer end of theshank 21, is provided with an enlarged disk head 33 which is threaded tothe shank 21 as shown in Figure 4.

In operation the container 1 I, being filled with a suitable flreextinguishing liquid, powder or the like, the device is operated byholding the part l8, in the hand of a user and is given one or twoswings and then thrown directly at the fire to be extinguished, thesteering device 20, guiding the missile straight to the point of thefire. When the disk 33, hits upon any hard substance it will drive theshank 21, in with force, causing the pin 3|, to discharge the cartridge,the concussion of which will shatter the disk 34, separating thecartridge from the material 35, in the container 1 I. The action of theexplosion will be such as to completely shatter the container and spreadthe extinguishing material.

When the missile is in flight, the steering device 20 which is formed ofa plurality of intersectingplates produces a drag. Since thisguiding-device 20 is attached by means of a flexible string, cord, orthe like to the rear end of the container II, the forward end of thecontainer will be that which contains the firing pin. Hence, the leadingedge or portion of the device which is the proper part of the mechanismto insure firing will be forwardmost in flight.

Changes in shape, sizeand rearrangement of details and parts such ascome within the purview of the invention claimed may be resorted to, inactual practice, if desired.

Having now described our invention that which we claim as new and desireto procure by Letters Patent is:

A fire extinguishing device comprising a friable substantiallypear-shaped container, a neck portion extending from said container, acap threadingly received on said neck portion, a bore in said capadapted to receive a firin cartridge therein, a firing pin slidablyreceived in said cap and the extremity of said neck portion, means fordirecting the flight of said container, means for flexibly joining saiddirecting means to said container, and said directing means includingintersecting substantially rectangular plates.
